The Fources Of Natural Selection And Genetic Drift

377 Words2 Pages

The four fources of evolution are; natural selection, mutation, gene flow and genetic drift.

Natural Selection consist a process in which the best adapted organism reproduce the most offspring and have better survival rates. These "best adaptive" traits carry forward to their offspring at a higher frequency.

Mutation are random changes in an organisms DNA that impact traits of the organism in a good, bad or neutral way. The changes are heritable and are a result of additions, deletions or substitution of the nitrogen bases of DNA.

Genetic Drift is a random process which dictates which alleles survive from one generation to the next.

Gene Flow happens when genes are combined from one population to another.

2. Balanced Polymorphism happens

    Evolution, in common terms, is descent through genetic inheritance, with change in physical and biological characteristics. Evolutionary theory attempts to explain why we see so many species in world that seem so diverse and yet, have enough similarities that imply a common origin. There are various mechanisms by which evolution occurs, including natural selection, artificial selection, gene drift, etc., but in the end, evolution is process by which every single species that exists today, was derived from the last universal ancestor. This perpetual system of change and advancement, shapes the both the biotic and abiotic aspects of the environment, and results in the creation and advancement of the complex communities that inhabit the biosphere.

Directional selection and disruptive selection differ because instead of the subject only going in one direction it will split off and go two different ways for example if some flowers and their colors. The main colors may be red, pink and white primarily, and the more dominate color being a pink flower. But if we remove the pink flower completely from the equation then the flowers will shift toward the dominant white color over the red.

    1126 Words  | 5 Pages

    Introduction The theory of evolution has been discussed, evaluated, and researched many times since the theory was first brought to light. Darwin’s theory of evolution is said to be divided into two parts, common decent and natural selection (Bouzat, 2014). Many research papers agreeing with Darwin’s theory comment on the diversity of a species and how they have descended from one common ancestor. Natural selection is a process in which species that are better adapted to the environment tend to survive and reproduce (Dictonary.com).

    Evolution is the process of change over time. It can be split in two questions, how did something living come from something that was not alive? And, how did things that were already living turn into other living things? Natural selection is when the “breeder: is the environment. This belief of natural selection came from Charles Darwin.

    Organisms can evolve to enhance their ability to catch prey, or flee predators. Coevolution occurs in a predator-prey relationship when the prey evolves in response to pressures exerted by its predator. The predator then evolves in response to the changes in the prey (or vice versa). Inheritable adaptive traits evolve through natural selection, the process by which organisms that have developed favorable traits are capable of surviving and reproducing at greater rates, thus passing their adaptive traits to their offspring. Birds and caterpillars have a predator-prey

And I will end with my opinion on why dreams may or may not be significant based on Flanagan’s theory and the treat simulation theory. I will also discuss the reasons why or why not dreams may have an evolutionary function.

In the wild, bananas were not easy to eat, they were oval with tough thick skin and hard seeds. In order to cut them open you would need a sharp knife and you had to spit out the seeds while eating them.

    ccording to lecture, the four mechanisms of evolutionary forces are mutation, natural selection, genetic drift, and gene flow. Mutation is defined by a change in the genetic code. This happens spontaneously. There are three major types of mutation. Point mutation is when there is a change in base substitution and may or may not produce a new amino acid.

    The first of the four forces of evolution is mutation. To me, mutation is a change in the normal genetic code. They occur a lot and can be purposeful or accidental. The second is natural selection and to me that has always gone along with survival of the fittest. So, it is changes from generations that increase survival.

    Imagine what would happen if we lived in a world where water was kept 8 feet off the ground and there was absolutely no way you could get it if you weren’t tall enough. Most likely, the short people would die off. The taller ones would multiply, and before long, instead of a population of people of all sizes, you would have a population of only tall people. Living things that are best suited, or adapted, to their environment survive and multiply. Those that are not, are unable to survive.

  • Darwin's Theory Of Evolution By Natural Selection

    Evolution is the process for how an individual species changes in their heritable characteristics through consecutive generations (Sollereder, 2016). Darwin’s theory of evolution by natural selection is basically an idea that the strongest survive or the survival of the fittest. The theory establishes that through natural selection it is determined which of a particular species will die prematurely and which members of the species are strong enough to survive and eventually reproduce. In nature, all animals must compete against each other for food, water and shelter. The species that is best adapted to the environment they are in are the species that will ultimately win out in the end.
